t=1....256
u(t)is white noise, e(t) is a zero mean uncorrelated random variable.
noise ratio(S/N)is four.
how to :
plot input output data u(t) y(t)
What i should do?
I only know get the whith noise x=random(1,256)
another i donot know ,please tell me how to do or read which books?
Thank you very much! | h****l
